Total Encryption also supports streaming mode, meaning Total Encryption can be used to encrypt and decrypt any kind of HTTP traffic. I also explain that since Total Encryption is completely controlled by VCL, we can extend the ideas of Total Encryption to create larger secured architectures.

Introducing Varnish Total Encryption

It seems like security is now more important than ever in our industry.

Things like firewalls, WAFs, advanced compilers, static analysis, SSL/TLS, and encryption, these are all examples of countermeasures that can greatly enhance the overall security of our systems. When used properly, these measures can neutralize entire classes of security vulnerabilities and security risks. It is with this in mind that we designed Varnish Total Encryption.
